I carry a S&W 640. Two o'clock iwb. Very comfortable and easy to carry. The shape works better with my body than semi's. I also have a PPS in .40 that I like. After dozens of handguns this is what I've whittled it down to in terms of carry.
For weighing 24 +/- oz unloaded, the 640 is slim and compact. I will say that in my experience, snubs take a lot more practice to get accurate with. But after years of carrying it now, the 640 is my go-to all around gun. If the PPS were as comfortable, I'd likely carry it more. The PPS is comfortable, but the 640 just works better for me. There's my 2 cents.
